Bracket structure for chute area of dry quenching furnace

Abstract

The invention relates to a bracket structure for a chute area of a dry quenching furnace. The bracket structure is formed by building a plurality of layers of bracket bricks; and a plurality of supporting pieces are arranged between every two adjacent layers of bracket bricks, the supporting pieces are hard supporting pieces, the thickness of the supporting pieces is the same as that of mortar joints, the top faces of the supporting pieces make direct contact with the upper layer of bracket bricks, and the bottom faces of the supporting pieces make direct contact with the lower layer of bracket bricks. The supporting pieces are placed in the refractory mortar joints between the bracket brick layers, so that the problems of sinking of the annular air duct and cracking of the chute partition wall caused by deformation of the bracket mortar joints and inaccurate bracket elevation control are effectively prevented, the masonry quality of the dry quenching furnace is improved, and the service life of the dry quenching furnace is prolonged.

Description

technical field [0001] The invention relates to the technical field of dry quenching coke ovens, in particular to a corbel structure of a chute area of ​​a dry quenching coke oven. Background technique [0002] Dry quenching has the functions of saving energy and reducing consumption, protecting the environment and improving the quality of coke, and has been widely used in recent years. CDQ coke oven is the key equipment of CDQ technology. It includes pre-storage area, annular air channel area, chute area and cooling area from top to bottom. Among them, the corbel of chute area 1 is made of multi-layer corbel bricks. 2 masonry (such as figure 1 shown), which is an important structure supporting the inner ring wall of the CDQ oven. In actual production, the corbel is easily worn, cracked or even collapsed due to heavy load-bearing, frequent operating temperature fluctuations, and long-term scouring by high-temperature coke and high-temperature circulating airflow containing...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a corbel structure in the chute area of ​​a CDQ coke oven. By placing support members in the refractory mud joints between the corbel brick layers, it can effectively prevent the deformation of the corbel joints and the inaccurate control of the corbel elevation. The sinking of the annular air duct and the cracking of the chute partition wall can improve the masonry quality and service life of CDQ coke ovens
